Compiler "hints" aren't showing for web site

Elements Oxygene

I don’t remember what those red marked lines are called when they have an error message in the code window, but when I create a Silverlight solution using the web SITE project, they don’t show.

When I compile the code, if the web project code has errors, they show in the error list and output window and those hyperlinks work, but when it takes me to the code, there are no red lines with suggestions for fixes.

Isn’t this supposed to work? I’m not sure if I’ve had this problem before or not since usually I don’t HAVE errors in the service part of the code.

In ASPX or ASPX.pas?

Neither?

In a class I created which the IDE put in App_Code folder.

Here is the code:

namespace VSDS.Data.Columns;

interface

   uses 
      System.Collections.Generic;

   type
      ColumnList = class
         public
            fColumnList : List<String>;
            constructor;
            function  GetColumnList( includeID : Boolean := False ) : String;
            function  GetColumnList( prefix : String; includeID : Boolean := False ) : String;
            function  GetColumnParameters( paramChar : Char; includeID : Boolean := False; includeName : Boolean := True ) : String;
            procedure InitColumnList; virtual; 
            procedure Remove( fieldname : string );
         end;

implementation

   constructor ColumnList;
      begin
      fColumnList := new List<String>;
      InitColumnList;
      end;

   method ColumnList.InitColumnList;
      begin
      // just a stub
      end;

   method ColumnList.GetColumnList(includeID: Boolean := false);
      begin
      result := GetColumnList( '', includeID );
      end;

   method ColumnList.GetColumnList(prefix: String; includeID: Boolean := false);
      var
         s    : String;
         I    : Integer;
         name : String;
         LeftBracket  : String := '[';
         RightBracket : String := ']';
      begin
      if prefix.Length > 0 then begin
         LeftBracket  := '';
         RightBracket := '';
         end;

      if includeID 
         then s := prefix + LeftBracket + 'ID' + RightBracket
         else s := '';

      for I := 0 to fColumnList.Count-1 do begin
         name := fColumnList[I];
         if length( s ) = 0 
            then s := s +        prefix + LeftBracket + name + RightBracket
            else s := s + ', ' + prefix + LeftBracket + name + RightBracket;
         end;

      result := s;
      end;

   method ColumnList.GetColumnParameters(paramChar: Char; includeID: Boolean := false; includeName: Boolean := true);
      var
         s    : String;
         I    : Integer;
         name : String;

      function IncludedName : String;
         begin
         if includeName 
            then result := '[' + name + '] = '
            else result := '';
         end;

      begin

      name := 'ID';
      if includeID 
         then s := IncludedName + paramChar + 'ID'
         else s := '';

      for I := 0 to fColumnList.Count-1 do begin
         name := fColumnList[I];
         if length( s ) = 0 
            then s := s +        IncludedName + paramChar + name
            else s := s + ', ' + IncludedName + paramChar + name;
         end;

      result := s;
      end;


   method ColumnList.Remove(fieldname: string);
      begin
      var index := fColumnList.IndexOf( fieldname );
      if &index < 0 then exit;
      fColumnList.RemoveAt( &index );
      end;

end.

Here is a compiler error:

c:\Users\Mark\documents\visual studio 2013\Projects\VSDSRest\VSDSRest.Web\App_Code\Database\DatabaseColumnLists.pas(33,4): error E52: (E52) Type "ColumnList" does not contain a declaration that matches this method signature: method ColumnList.GetColumnList(includeID: Boolean)

Not sure why it is complaining. The hyperlink goes to:

   method ColumnList.GetColumnList(includeID: Boolean := false);
      begin
      result := GetColumnList( '', includeID );
      end;

And it kind of grays out the first 4 characters of that first line, which means 3 blanks and the “m”?

I don’t know why it is confused. I copied this code from another solution that compiles fine (though I’m not sure if it has the red line problem.)

… time passes …

And another odd compiler error is this one:

Warning	15	(N7) Potential overload: method ColumnList.GetColumnList(prefix: String; includeID: Boolean): String	c:\Users\Mark\documents\visual studio 2013\Projects\VSDSRest\VSDSRest.Web\App_Code\Database\DatabaseColumnLists.pas	35	
Warning	16	(N7) Potential overload: method ColumnList.GetColumnList(prefix: String; includeID: Boolean)	c:\Users\Mark\documents\visual studio 2013\Projects\VSDSRest\VSDSRest.Web\App_Code\Database\DatabaseColumnLists.pas	35

… time passes …

I VERIFIED that that same code COMPILES in the other solution. Same “web site”, same .Net version project. odd

… time passes …

One difference I spot is that the one that works has more things in the uses. But I don’t see how that could change it.

… time passes …

Oh, I think I see. The one that doesn’t work has the code in the web site project. The one that compiles ok has that same code in a separate assembly that is USED by the web site project.

I guess I will refactor out what doesn’t work and see if it works outside the web site project.

… time passes …

So I made a new class library project. I CUT the folder that was under App_Code and pasted into the new class library project. It did the operation, but an Exception was raised and a dialog came up that didn’t give specific, just exception.

Now when I compile it, I get the red lines and other errors. I probably need to add some references. Perhaps that was the problem in the Web Site project.

… time passes …

When I told it to complete the classes, it didn’t put the STRING return value in the implementation. That looks to have been the problem the compiler was complaining about. (now that I can see some red lines)

So although refactoring made things easy for me, I presume the compiler should still be marking the lines in error when the source code is in the App_Code folder. And it doesn’t.
